From 8985814bb3732aaf7ce5bf892d2827bd4d854fc7 Mon Sep 17 00:00:00 2001 From: Michael Straube Date: Fri, 11 Nov 2022 09:37:31 +0100 Subject: [PATCH] staging: r8188eu: convert rtw_xmit_resource_alloc() to common error logic Convert the function rtw_xmit_resource_alloc() away from returning _FAIL or _SUCCESS which uses inverted error logic. Use the common error logic instead. Return 0 for success and negative values for failure.
